CHANGING PICTURES.

Speeiflcation of Letters Patent.

Application filed November, 28,1911 Serial No. 204,357..

To all whom it may concern 4 Be it known that 1, Gimme W. SAAL-- BURG, of New York, in the count of New York, and in the State of New ork, have invented a certain new and useful Improvement in Changing Pictures, and do hereby declare that the following is a'full, clear, and exact description thereof.

My invention relates particularly to pictures adapted to change, or if desired, give the efi'ect of motion. T

The object of my inventionis to provide a picture so arranged that by movement of the observer in regard thereto a changing effect or an effect of motion is produced in the picture. A further object'is to provide pictures of this character, which are so arranged that notwithstanding the change in "the angle of the observer to the picture, the

changing efiect or effect of motion remains substantially the same. A further object is to provide screens for pictures to accomplish this purpose having bars that are round so as to'have the same width notwithstanding the difierent angles of-the observer thereto. Further objects of my invention will appear from the detailed de-. scription thereof contained hereinafter.

While my invention is capable of embodiment in many different forms, for the. purpose of illustration I have shown only one form of my invention in the accompanying drawings, in which- Figure 1 is a. front elevation of a picture made in accordance with my invention;

Fig. 2 is a horizontal section of the same; Fig. 3 is a perspective view showing a modified form of my invention; and

' Fig, 4 is a plan view ofanother modified form of my invention.-

In the drawings 1 have shown a supporting board or back 1, carrying acomposite picture 2. The picture2is comprised of two sets of strips 3 a d 4 representing; respectively the portio of two difierent pictures. If the two different pictures are of entirely different subjects, a change from one picture to the other will be produced in'the operation-of the picture, and if they show two positions of a moving object, an efiect of motion will be obtained. I In front of the picture 2 and supported upon hinges 5 on a the back 1 there is a screen 6 com rised of :upper and lower horizontal panels 8, vertical panels 7 and 8 and vertical screen bars 9.- The screen bars 9are round or lifiatented.

semi-circular in cross-section so that they alwaysretain the-same size to the eye, not'-' withstanding the changing angle of the observer as he passes by the picture, or as the picture is moved past the observer. This gives a, much more uniform effect than if the bars did not retain the same width in the picture2 correctly upon the back 1, and

in the rear of the bars 9, said picture may be: located between two guides 10 and 11 at the two sides of the back 1. Any other by this means a changing efiect will be obtainable. Furthermore, in order'to position suitable'device. may. be provided instead,

such as marks, etc., on the back 1, in order to position the picture with regard'to the bars 9-.- In order to illuminate the picture .2, any desired lighting system may be used,

but by way of example, I have shown a series of electric lights 12 located above and in front of the screen 6, having a reflector 13.

' The picture 2 may be of any desired character, and may be, for example, taken photographically or produced by lithography. Furthermore, the pictures 2 may be made in any desired colors, and can be made on one sheet or in smaller squares as shown in Fig. 1. Furthermore, if desired, the entire picture may be made out of paper or stifl" card board as shown in Fig; .3, in which I have shown a picture. 14 having a-spacing member 15 separated therefrom by a scoring 16 and a screen member 17 separated therefrom by a scoring'having embossed hollow semicircular bars 19 separated by openings 20 and on the end thereof a spacing member 21 separated from the screen member 17 As shown in Fig. 4, I- may use instead of spacing members, a construction in which t e apparatus is made out of paper orstifi card board in which there-is a picture 21, located in curved position connected by a scoredportion' 22 to a screen 23 having bars 24 constructed in the same manner as the bars 19.

In the operation of my invention,-one of the composite pictures 2 is inserted on the back l--between the guides 10 and 11,: so'as to position the same, the screen 6 having first been moved out of the way upon the hinges 5. After the picture 2 has been attached in this manner, the screen 6 is swung over in front of the picture 2. When now the passerby views the picture 2 while he is passing, the picture will appear to change or give the effect of motion, according to the type of composite picture carried by the apparatus. In this way, if an effect of motion is desired, the picture will give very' eflectively and continuously the desired result. Furthermore, the same effect will be obtained if the picture is moved past the observer. 7

Similarly the modified form of my in-v vention shown in Figs. 3 and 4 may be printed and stamped out of a sheet of material and then folded to space the screen member from the picture. These forms of my invention are'especially advantageous for WlIldOVZ- display and I may .be made cheaply and expeditiously.

While I have described my invention above in detail, I wish it to be understood that many changes may be made therein without departing from the spirit of my invention. v

made up of alternating sets ofstrips each showing an individual picture, and a screen. 1n front of said composite picture having a plurality of spaced bars, the inner sides of i said bars being substantially semi-cylindrical in contour.

2. In combination, a composite picture made up of alternating sets of strips each showing an individual picture, and a screen infront of said composite picture having a plurality of spaced bars substantially circular in cross section.

- 3. In combination, a supporting back adapted to receive a composite picture, and a frame pivoted to said back and adapted to overlie said picture, said frame carrying a plurality of spaced bars, the inner sides of said bars being substantially semi-cylindrical in contour.

4. In. combination, a supporting back adapted to receive a composite picture, and

, a frame pivoted to said back and adapted to overlie saidpicture, said frame carrying a plurality of spaced .bars of substantially cylindrical shape.

In testimony that I claim the foregoing I have hereunto set my hand.
